Lewis Hamilton in Ferrari engine change at F1 Spanish Grand Prix - Ted Kravitz

Lewis Hamilton has opted to change his engine at the F1 Spanish Grand Prix, reverting from the new ADUO2 power unit to the previous specification. This decision aligns him with his Ferrari teammate Charles Leclerc, who had already made a similar switch to avoid a grid penalty. Hamilton had initially planned to use the new engine but changed course after Friday's practice sessions.

This engine change does not incur a grid penalty for Hamilton, as he is still within the allowed number of engine components for the season. Both drivers are now on equal footing regarding engine performance, which could impact their competitiveness during the race.
